Specification of Letters Patent.

Application filed August 29, 1914. Serial No. 859219 To all 1071mm itmay concern Be it known that I, WILLIAM H. Fnxzixs. a citizen of theUnited P tatcs. residing at Modesto. in the county of Stanislaus. Stateof California. have invented certain new and useful Improvements inShock-Ab sorbers; and I. do declare the following tt be a full, clear.and exact description of the same, such as will enable others skilled inthe art to which it appertains to make and use the same. reference beinghad to the accompanyingdrawings and to the characters of referencemarked thereon, which form a part of this application.

This invention relates to improvements in shock absorbers and isparticularly adapted to reduce the sudden expansion body of theautomobile has been thrown upward by reason of striking some obstructionin the roadway. It is a well-known fact that automobile springsaregenerally broken upon the second movement of the spring. that is,

4 the movement upward. and to overcome this tendency I have designed thehereinafter described device.

A further object of the invention is to produce a simple and inexpensivedevice and yet one which will be exceedinglyeffective for the purposes Ifor which it is designed.

These objects I accomplish by means of such structure and relativearrangement of parts as will fully appear bya perusal of the followingspecification and claims.

In the drawings similar characters of reference indicate. correspondingparts in the several views.

Figure 1 is as applied between the axle and the lower frame member ofthe vehicle. Fig. 2 is a side view of the friction frame. Fig. 3 is anend view of the friction frame.

Referring now more particularly to the a side view showing the device.

inside of the-guides i' and from thereon is placed below the guides T asat 9. To clamp this frame to the vehicle shaft I have pro-- vided bolts10 running through both sides of the frame as shown. I'pon oneside ofthe frame I have provided a long washer plate 11 slightly turned up onthe edgesas at 1:2 for a purpose as will hereinafter appear. The liner9' is also slightly turned back as at 13. Disposed in the buckle?) isanother strap ll having a sciies of hoes therein to provide for anynecessary adj ustment. To the end of this strap l I have fastened a hook15 to which is con. :cted a spring 16 fastened at its extreme end to abracket 17 rigidly riveted to the frame 1 of the vehicle.

ll'hcn the vehicle strikes an obstruction in the road the axle 1 will bemoved upwardly thereby allowing the spring 16 to pull the strap aroundthrouglr the frame. lpon the immediate return of the axle to its normalposition the strap and spring will have to return to their-normalposition and in doing this will have to act against the additional pullof the spring and alsothe friction of the frame as before described. Thefrictionwill be less when the shaft moves toward the frame of thevehicle because the strap being more or less stiff will tend to forceitself down around the friction. frame and this slack will beimmediately taken up by the spring 16.v of friction is obtained upon theupward movement of the shaft than upon the downward movement.

From the foregoing description it will be readily seen that I haveiroduced such a device as substantially ful the object of the inventionas set forth he in.

\Vhile this specification sets forth in detail the present and preferredconstruction of the device. still in practice such deviations from suchdetail may be resorted to as do not form a departure from the spirit ofthe invention.

Ila ving thus described my invention what I claim as new and useful anddesire to se-. cure by Letters Patent is:

l. A device of the character described comprising the combination with avehicle, of a frame secured to the axle of said vehicle. such framecomprising a pair of U- shaped guides spaced apart, the upper ends ofsuch U-shaped guides extending vertically with respect tosaid vehicle,acurved portion Patented Sept. 14, 1915.

In this, way a greater amount.
